Question about Ledvance Smart+ Wifi Classic
Does this product also have a "Last Light State" function? So the lamp remembers the last state even if you completely cut off the power supply by pressing the normal light switch? Unfortunately, many smart light bulbs do not have this function but always light up with full brightness after being switched off and on again - which is not desired for my application.
Helpful answer
In the meantime, I have tested the product myself.
If you switch the bulb off, it actually remembers the last settings (colour and intensity) and restores them as soon as there is power again. However, it does *not* remember if it was switched off before. Light bulbs that were switched off before a power failure, for example, switch on after the power failure with the colour and intensity that were selected when they were switched off. If you go on a trip and there is a power failure, all smart light bulbs will burn afterwards - possibly for weeks until you return.
Besides, they don't quite fulfil my use case. In my case, several light bulbs are switched on and off via a switch, and I wanted to pre-select which ones are switched on immediately (in everyday life) and which ones are added for certain moods. Unfortunately, this is not possible with this product either.

I have a comparable Ledvance bulb bought at Migros and it stays at the last setting (colour/intensity) even after being unplugged or after a power cut.
